Ford 1100 Hydraulic question

[mdrumr]

Hi all!

I have a quick question about the hydraulics on my ford 1100. I just changed the hydraulic filter on this unit (being the original filter 36 years old, 600 hours) I figured it was time for a swap. The hydro's were working well before but were a little slow (reason one to leave something alone)...anyway, the filter has been replaced. The fluid is at the appropriate level and there are no binds or kinks in any of the lines and the fluid was changed about 15 hrs ago (prior to me buying this tractor).

Here's the question, it has me puzzled...The hydro's are working but not on initial start up, the tractor has to run for about 4 or 5 minutes and you have to keep the moving the control lever back and forth and the arms will lower or raise. If you cut the tractor off, and the arms are raised they will stay raised. Also if the tractor is off for a minute or more you have to do the above again to get the lift arms to function.

I'm thinking there is an air bubble in the line somewhere?...if so is there a way to bleed it out? I have a shop manual for this tractor and can not find a procedure for it. Is this something that will work itself out eventually as the fluid cycles through?

If anyone is familiar with the hydro's on this tractor any help would be greatly appreciated!

Just an update to this thread for anyone who may have an 1100..

After 2 days of tinkering I found the issue with the hydraulics on this tractor, the canister that the hydraulic filter rides in was not sealed properly where it meets the coupler for the pump, after tons of searching I found one little pin drop of fluid seeping from the cover..my only guess is that the aluminum bolt stretched over time and would not go back as tight as original. I replaced the O rings around the canister when I changed the filter.

The fix, a 6 inch pipe clamp around the coupler and canister to compress everything together and the hydraulics work great now...$2 fix for a 2 day problem.

hopefully this will help anyone who may have similar problems!
